NAME¶
Data::Section::Simple - Read data from __DATA__
SYNOPSIS¶
use Data::Section::Simple qw(get_data_section);
# Functional interface -- reads from caller package __DATA__
my $all = get_data_section; # All data in hash reference
my $foo = get_data_section('foo.html');
# OO - allows reading from other packages
my $reader = Data::Section::Simple->new($package);
my $all = $reader->get_data_section;
__DATA__
@@ foo.html
<html>
<body>Hello</body>
</html>
@@ bar.tt
[% IF true %]
Foo
[% END %]
DESCRIPTION¶
Data::Section::Simple is a simple module to extract data from
"__DATA__" section of the file.
LIMITATIONS¶
As the name suggests, this module is a simpler version of the excellent
Data::Section. If you want more functionalities such as merging data sections
or changing header patterns, use Data::Section instead.
This module does not implement caching (yet) which means in every
"get_data_section" or "get_data_section($name)" this
module seeks and re-reads the data section. If you want to avoid doing so for
the better performance, you should implement caching in your own caller code.
BUGS¶
__DATA__ appearing elsewhere¶
If you data section has literal "__DATA__" in the data section, this
module might be tricked by that. Although since its pattern match is greedy,
"__DATA__" appearing
before the actual data section (i.e. in
the code) might be okay.
This is by design -- in theory you can "tell" the DATA handle before
reading it, but then reloading the data section of the file (handy for
developing inline templates with PSGI web applications) would fail because the
pos would be changed.
If you don't like this design, again, use the superior Data::Section.
utf8 pragma¶
If you enable utf8 pragma in the caller's package (or the package you're
inspecting with the OO interface), the data retrieved via
"get_data_section" is decoded, but otherwise undecoded. There's no
reliable way for this module to programmatically know whether utf8 pragma is
enabled or not: it's your responsibility to handle them correctly.
